Amazon to end support for older Kindles, prompting user outcry, BBC News. Kindle models released before 2012 will no longer be able to connect to Amazon. This means it won’t be possible—through official channels—to add new books to the device. Several sources are saying you can still transfer books via USB cable, but remember that Amazon has removed the option to download them? Thank goodness Calibre exists.

Analysis finds that Google’s AI Overviews are providing misinformation at a scale possibly unprecedented in the history of human civilization, Futurism. Conducted by the AI startup Oumi (a red flag, no doubt), the analysis found that AI summaries are wrong 9% of the time. That may not seem like much, but considering that these synthetic texts appear 5 trillion times a year… it’s a lot.

US: Meta is removing ads from lawyers offering to sue social media companies for psychological damages, Axios. Meta can’t seem to block ads for scams and illegal betting, though.

Microsoft blocks WireGuard updates. It’s the same case as VeraCrypt, which I mentioned yesterday: suspension of the developer’s Microsoft account, which prevents him from obtaining certificates from Microsoft, the only entity that can provide them for applications using Windows kernel drivers. Have you ever heard of Linux? Or macOS?

LittleSnitch for Linux. The coolest app I never really cared much about having (since it’s expensive), LittleSnitch, now has an official version for Linux. And it’s free! I’m so jealous… It’s just not entirely open source; the back-end (the part that makes the magic happen) is closed-source.

New video controls on Spotify. Remember when Spotify was just an app that played music? Someone there remembered, and in a rare concession, the app will soon include controls to disable all videos.

Tennis. A small command-line app that prints CSV tables to the screen in a very readable and pleasant format. Free and FOSS.

What's My ΔE(OK) JND?. Test your vision (and your screen’s color accuracy) by trying to identify the exact point that divides the two colors displayed on the screen. There are always two colors, even if it doesn’t seem like it.

LinkedIn hidden code secretly searches your browser for installed extensions, Cyber Security News. The amount of information that can be extracted from installed extensions is quite high. The snooping only works on Chromium-based browsers (Chrome, Edge, Opera, Vivaldi). Firefox and Safari users are still being spied on, but not through this channel.

A secure chat app’s encryption is so bad it is “meaningless”, 404 Media. The app in question is called TeleGuard. Every now and then a new “super secure” messaging app pops up, and it’s always wise to be on high alert in such cases. In any case, Signal is here—free, secure, tested, and proven.

Google AI Edge Eloquent. New app from Google—for now, only for iOS. It’s a dictation app that leverages the company’s local AI, from the Gemma line. Google promises to clean up the “hmm”s in speech and, in the near future, an extra keyboard to use the feature across all system apps. Free.

Netflix Playground. A new gaming app for kids, featuring various cartoon characters available on the platform. Available in the US and a few more countries; global rollout on April 28^th.

Blogosphere. Yet another directory of blogs — or rather, of posts. It’s kind of like Hacker News but with just posts from personal blogs.

list animals until failure. A little game where you have to list every animal you can remember. With each correct answer, you earn more time.

Microsoft forces update on computers running Windows 11 24H2, Bleeping Computer. Starting this week, the update to version 25H2 will begin automatically and is mandatory. The most concerning part is that Microsoft is using a “ machine learning-based intelligent” — in other words, AI. May the gods have mercy on Windows users 🙏

Samsung Messages will be discontinued in July, SamMobile. Samsung’s recommendation is for users to switch to Google Messages. Given that nobody outside the US uses SMS/RCS… who cares?

I redesigned the ENTIRE Apple Music UI. Liquid Glass might be good; it’s just that Apple isn’t putting in the effort. (Seriously, why isn’t Apple Music like the result of this video?)

How many products does Microsoft have named ‘Copilot’? I mapped every one. There are 75 — so far. There’s an interactive chart that breaks down the results by software type and shows the connections between them.

Artemis II astronauts have two Microsoft Outlooks running, neither of which works, 404 Media. Some earthly problems aren’t solved just by leaving Earth. It’s not yet known if either of them is working again. Listen to the audio. On another—more urgent—front, the Orion capsule’s bathroom “jammed” shortly after launch. The problem has been resolved.

Apple Expands iOS 18.7.7 Update to More Devices to Block DarkSword Exploit, The Hacker News. The update, which closes the vulnerability dubbed DarkSword, had initially been released only for devices incompatible with iOS/iPadOS 26.

Moods Faster. A new app to track your mood more quickly in Apple Health. It’s from the same creator of Remind Me Faster, an app that lets you create tasks in Apple Reminders more quickly. I sense a pattern here… For iOS and iPadOS, R$ 1.50/month, R$ 13.50/year, or R$ 33.99 for a lifetime license.

CSS or BS? So you think you know everything about CSS? This game tests your knowledge by presenting attributes and asking whether they exist or not.

Command Line Corner. A large collection of Linux terminal commands. Some are little-known (and super useful).

Nextcloud’s fork of OnlyOffice violates the AGPLv3 license, It’s FOSS. Nextcloud (German) and the hosting company Ionos created the Euro-Office fork, citing a lack of transparency and OnlyOffice’s Russian origins as their motivations. The OnlyOffice team is outraged, claiming that Euro-Office violates the AGPLv3. Nextcloud post; OnlyOffice post.

Meta and Ray-Ban announce a new generation of glasses for perverts. With new AI features that nobody cares about and cameras, the new glasses (two models) are optimized for prescription lenses and have removable nose pads. Abroad, launch on April 14^th for USD 499.

15 years of Waterfox. Waterfox was created to offer Firefox builds for 64-bit systems. The next major update will include a built-in ad blocker.

Stickers featuring Apple’s new mascot. Developer Simon B. Støvring created emojis of the Finder Guy, the mascot Apple created to promote the MacBook Neo on TikTok. (See images.) The download link expires in two days.

A supply chain attack affects the axios package on npm. This package has 100 million (!) weekly downloads. Attacks of this type on npm are rare, but they do happen frequently.

From rich text to video: RCS Universal Profile 4.0 arrived. In theory, the new version of RCS will enable video calls between Android and iOS phones. It also supports rich text (bold, underline, etc.) and settings for the quality of transferred images and videos. Despite the release, it will be a while before this version reaches our phones. Apple is still testing version 3.0, which was released in March 2025 and features end-to-end encryption…

Proton Meet. Proton, which used to be just an email service, is establishing itself as a “mirror” alternative to Google Workspace. The free version of Meet supports up to 50 participants in sessions lasting up to 1 hour.

Google allows changes to usernames. The “username” is what appears before @gmail.com. For now, only in the US. The name can be changed every 12 months.

Why the metaverse was doomed from the start. Some might say that now that the metaverse has imploded, it’s easy to make this kind of analysis, but this one is worth watching for the wealth of details condensed into a video of just 17 minutes. It has several insights that I missed when I watched the fateful metaverse presentation five years ago.

VitruvianOS. A Linux distro based on the old BeOS in active development.

Bluesky leans into AI with Attie, an app for building custom feeds, TechCrunch. An AI, powered by Claude, that creates custom feeds on Bluesky and apps compatible with the AT protocol at the user’s request. In the future, Attie may also create apps based on the protocol. For now, it’s in closed beta. Access it here.

Installing unverified apps on Android will carry over to new devices, Android Authority. This news, shared by a Google employee, makes things even better for those who want to use the “advanced flow” to install apps not verified by Google. The video answers other relevant questions.

cssDOOM. Doom recreated with CSS. (Works best on Chromium-based browsers.) Worth reading the creator’s post. Hot tip from Renan.

brrr. A new iOS app that lets you schedule and receive personalized notifications. USD 0,99/month or USD 9,99/year.

Wander. Click the “Wander” button, and a random personal website or blog will appear.

Meta and YouTube designed addictive products that harmed young people, jury finds, The Guardian. The fines are negligible, but what matters most here is the precedent this ruling sets.

GitHub will use user data to train AIs. This begins on April 24^th. If you don’t want this, you can (for now) disable sharing in Copilot’s settings. There are tons of options there; the one related to this new feature is apparently “Allow GitHub to use my data for AI model training.”

ClassicPress 2.7.0. The admin panel now supports “view transitions” (smooth transitions between pages) and there’s a new option to enable object caching. And, as always, the code is more efficient, with fewer JavaScript libraries and more pure JS. Can’t wait to use CP here on the Manual!

Samsung Browser for Windows. It’s now available worldwide, but for now the new “agentic” features are only available in South Korea and the US. Download here.

Font from the movie War Games. The font used on the terminals in the famous 1980s movie War Games.

“Liquid Glass” on Brazilian TV Globo, in 1994. Who would have thought, right? What’s worse is that it looks a lot like Apple’s Liquid Glass effects.

OpenAI shuts down the Sora app. It’s (was) its TikTok of AI-generated videos.

Disney scraps plan to invest USD 1 billion in OpenAI, Variety. Did you hear that *pop*? It’s the bubble bursting…

Wine 11 rewrites how Linux runs Windows games at the kernel level, and the speed gains are massive, Xda-Developers. Little by little, Linux is becoming the best platform for running games made for Windows.

Samsung announces the Galaxy A57 and A37. Samsung’s two mid-range models. The A57 features a slimmer body and AI capabilities never before seen in the A series.

Apple releases iOS 26.4, macOS 26.4, etc., MacMagazine. Safari got its beloved compact tab layout back (amen!) on macOS, and iOS now exchanges messages with Android via RCS with end-to-end encryption.

Krita 5.3 and 6.0. The 5.x series is compiled using the Qt5 framework, while Krita 6 uses Qt6. The main new features are full Wayland support, a redesigned text tool — allowing text to be edited directly on screen — and a new tool for creating comics.

TRS-80 Manual: Eliza. The brief manual for the first chatbot in history. And yes, even back then (1979) they called ELIZA “artificial intelligence.”

Morsify. This website translates typed text into Morse code in real time.

Samsung brings AirDrop support to Quick Share with Galaxy S26 series. Initially in South Korea, but other markets are next in line, as are other Samsung devices.

Ubuntu 26.04 ends 46 years of “silent” sudo passwords, Omg! Ubuntu. The next version of Ubuntu will display asterisks when typing passwords for sudo commands in the terminal. Previously (and in other distros), typing had no visual feedback “for security” — which, let’s face it, doesn’t make much sense anymore. Mint did this first.

Thunderbird Roadmap. Mozilla’s email client now has a public roadmap, broken down by platform (desktop, Android, iOS, and services).

Firefox 149. The main new feature, free VPN, is available in a few countries with a gradual rolling, but there are other new features and improvements that justify the update, especially the window with two sites side by side: right-click on one that’s in the background and select, from the menu, something like “Add to Split View”.

OpenShort 3.5. It’s not every day that a project announces “the biggest update in our 18-year history.” The main improvements are a new default timeline and an average 35% increase in speed, particularly in effects and frame processing. FOSS, free, and available for ChromeOS, Linux, macOS, and Windows.

Labels in Signal. Similar to WhatsApp, you can now set labels for yourself in Signal groups. Obviously, everything is end-to-end encrypted. Administrators have the option to restrict labels to themselves.

Pika. A color picker for macOS that displays the contrast ratio and offers a global keyboard shortcut. Available on the App Store for USD 4.99, or for free by downloading from GitHub (it’s FOSS).

100 Jumps. Hold the spacebar (or your finger on the screen) to adjust the square’s jump. For every three perfect jumps (in the center of the platform), you earn an extra life. Tip from Rafael.

Android developer verification: Balancing openness and choice with safety. Google has finally revealed what the “advanced flow” for installing apps from unverified developers will look like. It’s a bit of a hassle, but you only have to do it once. Better than I expected.

Our commitment to Windows quality. Big updates coming to Windows 11, such as changing the taskbar position, deciding when the computer restarts to apply updates, and the removal of Copilot from Notepad. It’s fascinating that Microsoft has messed up Windows 11 so badly that rolling the system back to… I don’t know, Windows 95 is seen as a major step forward, a “commitment to quality.”

PowerToys 0.98. The big news is a dock, or a second taskbar on the desktop. Microsoft should put these guys in charge of Windows. Speaking of which…

Creator Fast Track: A new way to quickly grow your audience and earn money on Facebook. Meta will pay a salary to content creators who post on Facebook. The bots that inhabit Facebook will see more sanitized content.

Gazette. A bridge that takes newsletters from a Gmail email to an RSS feed. Too bad it requires a lot of configuration involving Docker and the Gmail API.

Nightingale. A karaoke app that separates the vocals, transcribes the lyrics, and plays the song with the lyrics synced. Free, for Linux, macOS, and Windows.

GNOME 50 “Tokyo”. One of the most feature-packed updates in recent memory, with support for “fractional scaling” and variable screen refresh rates, new parental controls, various accessibility improvements, and a comprehensive file annotation system *.pdf in the Document Viewer (Papers) app.

Death to Scroll Fade!. He could have just used “lorem ipsum” to make his point. Web designers of the world, listen to this man.

Obsidian’s “Reading Mode.” Obsidian’s Web Clipper extension got a new feature that redesigns a web page to make reading easier. (Several browsers offer this natively.) I liked the look. To use “reader mode,” you don’t need to have Obsidian installed on your computer or phone.

Fedora Asahi Remix 43. The Linux distro for M-series Macs has gotten a major update, with support for the Mac Pro and additional features on the MacBook Pro M2 Pro/Max, as well as major updates to core components of Fedora, such as RPM 6.0 and DNF5.

Moody. Another ingenious use for the notch on recent MacBooks: as a teleprompter. (Too bad the app is so pricey.)

Aeris. A beautiful, real-time visualization of commercial flights. Unlike other apps and sites of its kind, this one is “3D” in the sense that you can see the altitude of the aircraft.
